The paper presents a design of an open-boundary quad-ridged horn to be used as a wideband scalable dual-linearly polarized probe for spherical near-field antenna measurements. With a new higher-order probe correction technique developed at the Technical University of Denmark, the probe will enable high-accuracy wideband antenna measurements at the DTU-ESA Spherical Near-Field Antenna Test Facility...
The validity range of the general high-order probe correction technique for spherical near-field antenna measurements is investigated. The results give evidence that the technique is reliable for antennas with cross-section dimension of up to at least 60 wavelengths.
